OVERHAUL AND REPLACEMENT GUIDE
The first overhaul
or
replacement should be performed not
later than the required period. The condition of the item
at
the
end
of
the first period can be used as a criterion for determin-
ing subsequent periods applicable to the individual airplane
or fleet operation, providing the operator has an approved
monitoring system.
The time periods for inspections noted
in
this handbook are
based on average usage
and
average environmental condi-
tions.
SPECIAL CONDITIONS CAUTIONARY NOTICE
Airplanes operated for Air Taxi or other than normal opera-
tion, and airplanes operated in humid tropics
or
cold and
damp climates, etc., may need more frequent inspections for
wear, corrosion and/or lack of lubrication.
In
these areas,
periodic inspections should be performed until the operator
can
set
his own inspection periods based on experience.
NOTE
The required periods
do
not constitute a guaran-
tee that the item will reach
the
period without
malfunction as the aforementioned factors can-
not
be
controlled by the manufacturer.
NOTE
On-condition items
are
to be overhauled or re-
placed when inspection or performance
of
these
items reveal a potentially unsafe or unservice-
able condition.
